My mother has an inclusion cyst on the left gluteal region. There is Well defined mixed echogenicity lesion subcutaneous planes of left gluteal region, it roughly measures 8x4x4 cm in size. She got the put removed but it still has residue left. She has been told to undergo surgery to remove the residual cyst wall that has infection . I am keen to know If a surgery is required for this or it can be managed with medication ?
